Earth’s magnetic field and rotation are producing electricity — just not how anyone expected
Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...
The magnetic compass is the last unknown sense in migrating animals. For some scientists, the monarch butterfly is leading ...
Abstract: This study presents a scale-free and phase-agnostic method for detecting interturn short-circuit faults (ISCFs) in the stator windings of permanent magnet synchronous motors (PMSMs). The ...
The RTV 31 hovertrain was expected to be even faster than Japan’s bullet train, but now it is rotting beside a railway line ...
